I am trying to parse a text file I loaded in Actionscript 3.0, help please

All I can find information on fo开发者_StackOverflow社区r the URLLoader object in Actionsript 3.0 involves loading XML files, which I don't want to do. I'm trying to load in a .txt file that I want to parse, line by line with each line being delimited by a comma. Anyone know a method of doing this or a place where I can find some information on how to do this? Thanks!

Look at the String's split() methods for start. It splits a string into an array based on a delimiter. In your case you would access each line as an element of the array returned by using split() and the comma character.

e.g.

var csvLoader:URLLoader = new URLLoader(new URLRequest('yourFile.csv'));
csvLoader.addEventListener(Event.COMPLETE, csvLoaded);

function csvLoaded(event:Event):void{
   var lines:Array = String(event.target.data).split(',');
   var linesNum:int = lines.length;
   for(var i:int = 0 ; i < linesNum; i++){
      trace('line ' + i + ': ' + lines[i]);
   }
}

You can use event.target.data.split(','), I used String to make split()'s origin obvious.

@dhdean's tutorial is pretty cool, bare in mind that is as2.0, so there are slight differences with loading the file, but parsing strings should be pretty much the same in as2.0/as3.0

Depending on your comfort level with as3.0 you might want to have a look at csvlib.

For any example that you see that works with XML files, you just have to delete the line that says "new XML()"

For example, in this example at http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/URLLoader.html#load()

You have the following example:

   private function loaderCompleteHandler(event:Event):void {

            try {
                externalXML = new XML(loader.data);
                readNodes(externalXML);    
            } catch (e:TypeError) {
                trace("Could not parse the XML file.");
            }
    }

Your text data is in the variable "loader.data"

Using

var arr:Array = loader.data.split(",");

will return an array that was delimited by a comma.
